Abstract (en)
[origin: CN111876190A] The invention relates to a multi-chain plant for producing olefins from oxygenates and to a corresponding method, in which a plurality of reactor trains are arranged in parallel and run in parallel, each reactor train comprising one or more catalyst-containing oxygenates to olefin (OTO) reaction zones, at least one of the parallel reaction zones may be operated in a regeneration mode, while the OTO synthesis reaction may be performed in other reaction zones in parallel with the reaction zone. Partial product streams obtained from these individual reactor systems operating in the synthesis modeare discharged via partial product conduits combined into a complete product conduit using connecting means; then the product streams are compressed by a compressor and are separated into a pluralityof olefin-containing hydrocarbon fractions using a multi-stage aftertreatment instrument. The inventive configuration of the apparatus and process reduces pressure drop and thus increases the yield of short chain olefins, such as propylene.
